Tardigrade Admin · Accepted Answer

In the given graph, AB represents no change in temperature with time. It means ice and water are in thermal
equilibrium. BC shows the change in temperature with time. CD represents a constant temperature

(100℃)

with time.
It means, water and steam are in thermal equilibrium at boiling point.

Q. The given diagram depicts the phase change of ice on heating. In the graph temperature has been plotted against time elapsed. Which of the following statements is correct?

A B represents ice and water are not in the thermal equilibrium

At B water starts boiling

At C all the water gets converted into steam

CD represents water and steam in equilibrium at boiling point

In the given graph, AB represents no change in temperature with time. It means ice and water are in thermal equilibrium. BC shows the change in temperature with time. CD represents a constant temperature (100℃) with time. It means, water and steam are in thermal equilibrium at boiling point.

Which of the following statements is correct?

In the given graph, AB represents no change in temperature with time. It means ice and water are in thermal
equilibrium. BC shows the change in temperature with time. CD represents a constant temperature $(100℃)$ with time.
It means, water and steam are in thermal equilibrium at boiling point.
